If I ever had any vanity, then I definitely lost it by being on television. It doesn't do you any favours in terms of showing you what you look like and what your emotions are.

I like New York. There are similarities with London that make it feel rather like home, but at the same time it's slightly fictional.

Gardening has just sort of grown on me. I find it therapeutic. And I like smelly things.

I am attached to the west coast of Scotland - it's gorgeous to look at and challenging. You have to contend with the possibility of being blown away or rained on. And in the summer months you can be eaten alive by midges.

I do find myself surprised by the comedy shows that seem to have the same joke week in week out.

I've always liked trees. And then, growing up, I took an interest in ecology, hedges being destroyed, the landscape being turned into prairies.

My favourite plant is the foxglove. I think they are a perfect balance between being a garden plant and a wild plant, as at home in woodland as they are in a city.
